Alan,
I made one very similar to yours and it works very well on the 8 x 10. However, when I put it on the 8 x 20, some lenses have problems. The 19" red dot artar, which doesn't project out the back of the lens board at all, is located too far out in front of the packard (about 3/4") and the front end of the bellows begins to cut off the wide sides of the image about an inch on each side. I'm in the process of mounting a packard directly to the back of the 19" lens board to fix this problem. My other lenses that do project out the back of the lens board are close enough to the packard shutter so there is no problem.
Jim - you might want to be aware of this when it comes to your 8 x 20.

Jim, here are a couple of pictures of a similar setup for my 8x10 B&J. Also addes as a bonus, the lens shade I made to cut some of the light from the Nikkor 480mm lens. Best, tim
